Abstract

Breast cancer screening is an evolving area as there is still need of finding the ideal screening modality that fit the community demand of mass screening. The aims are to evaluate the validation and feasibility of EIT against gold standard mammography and to determine women pain perception towards both imaging methods. Women underwent screening mammography were selected for EIT imaging. The pain score were taken after each imaging session. Two independent raters were chosen to interpret image findings of EIT. 164 women were successfully selected for the study. 48.17 of subjects were classified as normal (group 1) with no significant findings (BIRADS 1); and 51.83 of subjects were classified as abnormal (group 2) with significant findings of either benign or suspicious of malignancy (BIRADS2). EIT sensitivity and specificity against screening mammography for rater 1 were 69.41 and 63.29, whereas for rater 2 were 55.29 and 56.96 respectively. The reliability for each rater were found to range between good to very good with Kappa of 0.88 for rater 1and 0.79 for rater 2 (p
